Electrical design packages, produced to your standards.
An electrical design company in Belgrade, working alongside engineering offices, rolling stock builders and panel builders across Europe.
We take defined design packages off your desk and hand them back ready to issue.
Produced in your environment
Your CAD setup, your layer conventions, your title blocks and drawing numbering. The files come back native and editable, not flattened.
You keep the responsibility
You hold the client relationship and the design responsibility. We supply the production and the calculation standing behind it.
Inside your working day
We work in the same time zone as Zurich, Vienna and Paris. Questions are answered the same working day, in English, French or Serbian.
What we verify on every package
A drawing set is only as good as the checks behind it. Our calculations document each of these, so your engineer of record and the reviewing authority can follow every result.
Current-carrying capacity corrected for installation method, grouping and ambient temperature.
IEC 60364-5-52Every conductor survives the let-through energy of its protective device.
IEC 60364-4-43Fault loop impedance checked on every circuit so faults clear in time.
IEC 60364-4-413 % for lighting and 5 % for other uses, from the origin of the installation.
IEC 60364-5-52Heat dissipation of every panel verified against its enclosure and ventilation.
IEC 61439-1Cables and materials matched to the hazard level of the vehicle.
EN 45545-2Building services and infrastructure
For consultancies, lighting studios and design and build contractors working on hotels, residential, healthcare, aviation and commercial projects.
Low voltage distribution
Load schedules and diversity, single line diagrams, board schedules, cable sizing with voltage drop and thermal verification, protection coordination and discrimination studies, short circuit calculation, earthing and equipotential bonding, lightning and surge protection, small power and lighting layouts, containment and riser design, and vendor-neutral specifications for procurement. Calculation is carried out in whichever manufacturer ecosystem you already work in, so the output is directly verifiable by you and by the reviewing authority.
- HD 60364 / IEC 60364
- EN 62305
Lighting design production
The technical work behind a lighting concept, for studios and architects who hold the design intent and need the calculation, compliance and documentation delivered to programme. Photometric calculation in DIALux evo, luminaire schedules with equivalence assessment, emergency and escape lighting, control zoning, installed power density checks, rendered output for client presentation and technical comparison of tender offers.

Photovoltaic systems
String layout and yield simulation in PVsol, low voltage and protection design, grid connection documentation, off-grid and hybrid systems, and solar street lighting.
Railway rolling stock
For rolling stock builders, refurbishment workshops and rail engineering consultancies, on new build, retrofit and heritage conversion programmes.
Electrical schematics and revision sets, cable schedules and harness routing, low voltage distribution and protection, battery and charger sizing, interior and exterior lighting design, earthing and bonding, interface control documentation, and as-built documentation following commissioning.
Retrofit work includes survey of existing installations, reverse documentation of undocumented systems, and integration of modern distribution into historic vehicles where space and aesthetics are constrained.

- EN 45545
- EN 50126 series

Current rolling stock work is under confidentiality and can be discussed directly under a non-disclosure agreement.
Control panels and machine building
For panel builders, machine builders and system integrators with workshop capacity but not design capacity.
Schematic and enclosure design in EPLAN Electric P8 and Pro Panel. Complete schematic sets from a functional description or a marked-up predecessor drawing, terminal and cable plans, parts lists with structured article data, three dimensional mounting plate layout, wire routing and duct fill, thermal assessment and ventilation sizing, revision handling against change requests, and as-built updates. Where the mechanical interface matters, enclosure and cut-out geometry is developed and checked in Creo Parametric.

One house
Buildings, rolling stock and control panels are three different worlds of standards, but they are the same electrical engineering and they pass through the same team. Nothing is handed to a third party, and nothing waits in another studio's queue.
The Greeks kept every craft of the forge in one workshop under Hephaestus, and gave engineering the letters it still calculates in. The company is named for the same idea. Omni: all of it, in one place.
Selected work
Selected projects delivered by our founder, David Soumano, in collaboration with the companies named on each project.

Budget estimate
Answer a few questions about your project and get an indicative fee for the electrical design in a minute. The fixed price follows once we have seen your drawings.
Non-binding, excluding VAT where it applies. Site visits and travel are quoted separately. Railway projects are priced on their scope: write to us. The estimate is calculated in your browser; nothing is sent until you choose to write to us.
Working with us
The terms we bring to a first commission, before anyone asks.
Pricing
Work is normally a fixed fee against a written scope and a named deliverable list, with a defined revision allowance. Framework agreements with call-off packages suit clients with recurring demand. Day rates are available where the scope genuinely cannot be fixed in advance.
Confidentiality and intellectual property
We sign your non-disclosure agreement before receiving project information. All intellectual property in commissioned work passes to you on payment. We do not reuse client drawings, details or specifications on other commissions.
Design responsibility
We support your engineer of record. We do not seek to displace you in the relationship with your customer, and we will not approach your customers.
Insurance
Professional indemnity cover is arranged to the level your procurement requires, with a certificate provided before the first commission.
